The "hottest" code is the one that best fits your specific goal. For pure learning and education, start with the Ferreira, Bower, or Elementary repository. If you need a flexible and powerful platform for your own research, dive into MooAFEM or the new galerkin framework. For solving specialized problems like topology optimization or multiscale analysis, the dedicated packages mentioned above are invaluable. And if your priority is a user-friendly, industrial-strength environment for rapid prototyping and multiphysics simulation, FEATool Multiphysics is the clear industry favorite. Happy coding
